  7. Abstract:
  8. Inventory problems are studied for a long time and many authors have investigated models with shortage phenomenon. To reduce inventory holding cost or decaying items we can have a shortage period in witch a part of demand is backordered; Although we pay fines to pending costumers, as shortage period is extended a larger portion of them will refuse to wait until replenishment. So, calculating an optimal duration for on hand inventory and shortage period with respect to inventory costs has became an interesting research field. However, related studies are rarely appeared in supply chain researches, where an integrated inventory model for a supplier and a retailer is proposed; especially when a variable backorder rate as a function of shortage duration is one of assumptions. From this point of view, we have proposed some models with particular assumptions about depending demand on stocked volume and deterioration and all of them consist of an integer decision variable beside two continuous. To find global optimal variables, we used a heuristic algorithm on the basis of incrementing integer variable one by one and finding local optimal values for two others with respect to some propositions and interesting model properties. We also developed the related codes in Maple 13 software and the results of numerical examples showed that when the decisions are centralized using policies like vendor managed inventory, in most situations total supply chain cost is reduced.
